  6. superprismatic added an answer to a question The kindest (shortest) cut of all   

    @Bonanova or anyone else who may have an interest in this:
    Do you have a proof that that circular arc is the shortest? Conceivably, a piece of a trigonometric curve, or exponential curve, or another conic section may be shorter. The possibilities are endless.
